Maria Sharapova barely missed a beat in her first match back in Melbourne since a failed doping test in 2016 resulted in a 15-month ban from tennis, closing out her 6-1, 6-4 victory over Tatjana Maria on Tuesday with an ace.

Grigor Dimitrov hurdled the net to check on the welfare of his opponent Kyle Edmund and then helped him to a courtside chair for treatment. Two games later, the defending champion had secured his spot in the Brisbane International semifinals.
